Abstract : This report describes the methods and computer programs developed for determining the combined viscid-inviscid flow fields over generalized three-dimensional bodies. The inviscid flow field is determined by a three-dimensional method of characteristics program, while the laminar boundary layer is determined by a three-dimensional explicit finite - different method. The complete program, which can treat either ideal - or real-gas flows, is highly automated and provides many optional paths of analysis. This volume of the report (Volume II) discusses in detail the actual computer program. Part I discusses the make up of the input data, the format of the output data, and the estimation of the running time. Also provided in Part I is a dictionary of all essential FORTRAN variables.
